Key applications

  • Priming under water-based waterproofing membranes
  • Priming new and aged concrete
  • Priming rendered & masonry surfaces
  • Priming precast concrete panels
  • Intercoat bonding for repair & maintenance of existing membranes
  • Surface preparation for adhesives & sealants

Surface suitability

  • New and aged concrete
  • Rendered surfaces
  • Masonry structures
  • Compressed fibrous cement (Fibro)
  • Porous and non-porous substrates (confirm with rep)
  • Existing waterproofing layers
  • Precast concrete panels

Not recommended for particle board or chip board. Not a vapour barrier — moisture will cause blistering and peeling. Not suitable for sunlight exposure; must be protected from sunlight after 48 hours of full cure.

Frequently asked questions

View all FAQs
  • Where is ACTFLEX 600 Primer used?
    Compatibility

    600 Primer is a hybrid solvent-based moisture-cured primer for both porous AND non-porous substrates - concrete, render, precast, fibre cement, and existing waterproofing systems. The hybrid chemistry handles the substrates most other primers can't span.

  • Coverage and cure?
    Performance

    Coverage is 4-6 m² per litre. Touch-dry in 15-30 minutes, full cure in 6 hours at 25°C/50% RH. Apply 50-100 microns DFT. Ready-to-use - no mixing or dilution required.

  • Which membranes is it compatible with?
    Installation

    Compatible with both water-based AND solvent-based ACTFLEX membranes - one primer for the whole range. This is the workhorse Forspec primer for typical project work.

  • Application temperature range?
    Compatibility

    Apply between 10-26°C ambient. Same-day reactivation is possible if the can has been opened recently. Once cured (6 hours), prime is ready for membrane application.

  • Is 600 Primer a vapour barrier?
    Compliance

    No - 600 Primer is NOT a moisture vapour barrier. For projects with significant moisture vapour issues (high RH concrete, suspect slabs), use ACTFLEX MB200 or EP 250 to block vapour transmission.
